ABSTRACT:
A printed circuit board has an inverted-L-shaped antenna pattern, which is provided with a conductor pattern connected to a ground pattern, so formed thereon as to be in close proximity to the outside of an inverted-F-shaped antenna pattern which is provided with a conductor pattern connected to a feeding point and with a conductor pattern connected to a ground pattern. By making resonance frequency of each of the inverted-F-shaped antenna pattern and the inverted-L-shaped antenna pattern different, it is possible to compose a frequency antenna using different frequency bands.
